· Volkswagen recalled 840,000 vehicles DSG transmission technology to provoke controversy

It is understood that Volkswagen (China) Sales Co., Ltd., FAW-Volkswagen, and Shanghai Volkswagen have announced that they will recall more than 840,000 defective vehicles due to safety hazards in transmissions and lights. Of these, 640,000 vehicles involved the controversial DSG transmission.

According to the announcement of the AQSIQ website, on November 13th, 207,778 Volkswagen cars were recalled due to hidden lights. On the 14th (yesterday), due to the hidden danger of the transmission, Volkswagen announced that it would recall 640,309 vehicles from the 25th. The two recalls involved all models of Volkswagen, and the AQSIQ website announced that the vehicles used in the transmission were recalled by the transmission. Synthetic oil can cause a fault in the power supply line inside the transmission. In extreme cases, the transmission failed to work properly. The reporter consulted the automotive experts of the relevant department's defective product management organization.

In this regard, some experts in the industry said that in fact some of the components of certain additives in synthetic oil do affect the corresponding use of DSG. In general, the base oil itself has no problem, but some of the oil is added for special needs. The additive will form some electrochemical reactions with certain materials under certain special conditions, causing some problems.

So the recall of many models is due to the DSG transmission, is the DSG transmission technology mature? Xiaobian has compiled some opinions on the Internet as follows:

Related experts: "It should be very mature in mechanical design, but in some respects it should be said that there are still some shortcomings, and it needs to be continuously improved and improved according to the actual exposed problems."

Jia Xinguang, a well-known auto industry commentator: "The recall of the public is relatively large. Because of the implementation of the Three Guarantees, he should try to solve the problem first. This is the reason for the recall now."
